“…The readily organic contents in vermicompost facilitate the process of mineralization and nutrients cycling regulated by microbes in the soil. It also enhanced soil aeration and aggregation which played a key role in the proliferation of soil aerobic microbes [ 44 , 46 ]. Better aggregation also increases the water holding capacity.…”

“…Better aggregation also increases the water holding capacity. Plants usually take nutrients through this water uptake, thus better water availability by application of vermicompost also played important role in the improvement of crops productivity [ 44 , 46 ]. Similar results were also noted in the current study where soil N, P and K were significantly increased where VC was applied as a sole and combined amendment with BC and NPK.…”

Maize productivity and soil nutrients variations by the application of vermicompost and biochar

et al. 2022

Poor soil organic matter is one of the major causes of the deterioration of soil health. Most soils fertility is also decreased when enough organic carbon is not present in the soil. Maize is most susceptible to this poor soil fertility status. A significant amount of maize growth and yield is lost when it is cultivated in low organic matter and poor fertility soil. To overcome this issue organic amendments can play an imperative role. Biochar and vermicompost are organic amendments that can not only improve organic residues but also increase soil nutrient concentration. The current experiment was conducted to explore the sole and combined application of both organic amendments with recommended NPK fertilizer. Four treatments were tested i.e., control, biochar (BC1), vermicompost (VC1) and VC1+BC1 with and without nitrogen (N), phosphorus (P) and potassium (K) in the experiment. Results showed that VC1+BC1+NPK performed significantly best for improvement in maize plant height (6.25 and 3.00%), 1000 grains weight (30.48 and 29.40%), biological yield (18.86 and 43.12%) and grains yield (30.58 and 39.59%) compared to BC0+VC0+NPK and control respectively. A significant improvement in soil N, P and K also validated the efficacious role of VC1+BC1+NPK over BC0+VC0+NPK and control. Treatment VC1+BC1+NPK is recommended for the achievement of better maize growth and yield in poor organic matter soils. More investigations are suggested in variable climatic conditions to declare VC1+BC1+NPK as the best amendment compared to control for enhancing soil N, P and K status as well as maize productivity.

“…Thus, the negative environmental impacts triggered by the intensification of GVP have gradually become prominent [1]. Previous studies indicated that excessive N input disrupted nutritional balance, and lowered soil pH, microbial activity, and diversity [5][6][7]. Furthermore, N fertilizer-induced soil nitrous oxide (N 2 O, a long-lived and potent greenhouse gas) and nitric oxide (NO, atmospheric photochemical pollutant) emissions have received widespread attention owing to the robust and steady rise of emission factors [8].…”

“…Recent meta-analyses revealed that biochar application decreased agricultural soil N 2 O and NO production by 38% and 8.3%, respectively [13,16]. Additionally, biochar interacting with N can enhance soil quality and crop production via (1) slowing soil acidification [17], (2) regulating soil structure and aggregate formation [18], (3) enhancing soil hydraulic properties [19], (4) improving nutrient recycling and utilization efficiency [20], (5) stimulating root growth and photosynthetic performance [21], or via a combination of the above mechanisms. However, due to various soil types, biochar properties, and experimental conditions, there is still no consensus on N 2 O and NO mitigation, crop production, and soil quality.…”

Biochar amendments have been widely used in agricultural soil for lowering N2O and NO emissions while improving soil fertility and crop performance. However, a thorough understanding of the longevity of the favorable effects would be a prerequisite for large-scale biochar application in agriculture. We conducted a three-year greenhouse vegetable trial in Southeast China to systematically investigate the impacts of biochar mixed with nitrogen (N) on soil N2O and NO emissions, vegetable performance, and soil fertility at an interannual scale. The field experiment was established in November 2016 with biochar (0, 20 and 40 t ha−1; C0, C1, and C2, respectively), applied once without/with 240 kg N ha−1 urea (N0 or N1, respectively). Soil N2O and NO emissions were monitored during the spring vegetable cultivation period, and vegetable yield, quality, and soil properties were measured after harvests in 2018, 2019, and 2020. Results indicated that N application significantly increased N2O and NO emissions and vegetable yield throughout the trial period. Biochar combined with N generally reduced N2O and NO emissions and emission factors while increasing the vegetable yield, leading to lower yield-scaled N2O and NO emissions in 2018 and 2019. Biochar markedly enhanced soil pH and organic carbon and persisted, but generally had no significant effect on N use efficiency (NUE), vegetable quality, and soil fertility index (SFI) among treatments in over-fertilized vegetable fields. Based on our results, biochar application at 20 t ha−1 combined with N seemed to achieve the highest agronomic and environmental benefits for intensive vegetable production in Southeast China.

“…About 30% of the world irrigated lands that produce approximately one-third of the crops are affected by salinity [ 13 , 14 ]. In Korea, lily cultivation is carried out by protected cultivation [ 8 ], which is exposed to excessive input of fertilizer [ 15 ]. The contribution of a large amount of chemical fertilizer and compost increases salt accumulation in the rooting zone, and decreases the soil’s chemical and physical properties [ 16 , 17 ].…”

Salt stress is a major constraint of crop productivity because it reduces yield and limits the expansion of agriculture. This study investigated salt tolerance in 26 cultivars of cut lilies (Lilium hybrids) by examining the effect of salt stress on the growth and morphological characteristics of flowers and leaves and their physiological properties (chlorophyll a fluorescence). Salt stress significantly affected the growth and development of cut lilies. Canonical discriminant analysis indicates that the middle leaf width, number of flowers, first flower diameter, petal width, and chlorophyll a fluorescence were correlated with salt stress, whereas plant height, the middle leaf length, days to flowering, and sepal width were less affected by the stress. The cultivars examined were divided into three groups: Group 1 included the salt-sensitive cultivars, which failed to develop normal flowers; Group 2 included cultivars sensitive to salt stress but tolerant to osmotic stress; and Group 3 was the salt-tolerant group, which developed commercially valuable flowers. In conclusion, the cultivars contained a variable range of cut flower characteristics and growth traits that can be employed for lily breeding programs and as material for molecular mechanisms and signaling networks under salt stress.
